Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture using a fluorescent lamp.

Conventionally, in this type of lighting equipment, wiring parts such as a starter socket and a switch are assembled together with a ballast into a case of the lighting equipment, and a reflector is attached to cover the bottom surface of the case. Wiring parts such as a starter socket and a switch built into the case may be unitized as shown in, for example, Japanese Utility Model Application Publication No. 56-153022.

That is, each wiring component is integrally provided on one side of a first board made of an insulating material, and a conductive part and a circuit part that face into each wiring part and act as a contact piece or a switch contact are provided on the other side of the board. A second substrate made of an insulating material, which further covers this conductive plate so that undesired live parts are not exposed, and holds the conductive plate together with the first substrate. It consists of:

However, in such a configuration,
The wiring component is a unitized component that is independent of the reflector and case, so it requires an assembly process as a wiring component, and since it has a switch section, at least one side of the board has a switch section. It has to be made of a material that can withstand the generated sparks, such as a thermosetting resin, and has drawbacks such as high material cost.

Therefore, it is possible to reduce the cost by forming the reflective plate from a relatively inexpensive thermoplastic resin, etc., to have the function of a conductive plate holding substrate, and reducing the amount of thermosetting resin as much as possible. It was difficult to make direct electrical connections between the parts fixed to the boards, and automatic assembly was especially impossible.

This invention has been made in view of the above points, and includes a reflective plate made of thermoplastic resin having an inclined part on the inner surface thereof with a downward slope on the side facing the circuit part connected to the ballast terminal of the conductive plate. The case is provided with a ballast mounting hole for attaching the ballast positioned by the ballast positioning rib, and a conductive plate is placed on the switch base that is placed and fixed on the bottom of the reflector. Then, the ballast is placed on the ballast with the terminals facing the circuit section of the conductive plate from above the sloped part of the ballast positioning rib, and the ballast is clamped and fixed between the reflecting plate and the fixing member. Connect the terminal and the circuit directly, then combine the case with the reflector and screw the ballast mounting screw inserted into the ballast mounting hole into the ballast mounting hole. To provide a lighting device in which the ballast is fixed to the inner surface of the case at a distance from the reflector, thereby reducing costs, facilitating start-up assembly, and preventing the reflector from deforming or discoloring due to the ballast. The purpose of the present invention is to provide a method for manufacturing lighting equipment that can achieve the desired results.

Because it slides after hitting each positioning,
Easy to determine location. Furthermore, stabilizer 130
When the is screwed onto the case 140 and pulled up to the bottom part 140a, since the inclined part 190 is attached, it is difficult to position the thermoplastic resin material, and when the fluorescent lamp 186 becomes hot during lighting, the ballast 130 Since the base outer plate 137 is sufficiently spaced apart, each positioning is not affected by deformation, discoloration, etc. due to heat. In addition, a notch 22 is provided in the part of the positioning rib 22 of the reflector 1 on which the stabilizer is placed.
a, which has the effect of holding the ballast 130 horizontally by avoiding swelling due to uneven coating of the outer insulation paint that occurs during the manufacturing process of the ballast 130.

Note that FIG. 21 shows an example in which a lighting fixture is suspended by a cord, and the plug 170, engagement portion 171, and stopper 172 are the same as those described above. And 17
5 is a round cord derived from the plug 170, 1
76 is a cord locking piece that is locked to the round cord 175, and 177 is a cord hanger into which the round cord 175 is inserted and received, and is used to adjust the hanging height from the ceiling. The cord hanger 177 is engaged with the cord cover engagement hole 152 of the case 140. 178 is a cord locking tool for locking the round cord 175, and 179 is a hook rosette connected to the tip of the round cord 175.

As explained above, according to the present invention, the use of thermosetting resin using thermoplastic resin for the reflective plate can be suppressed, material costs can be reduced, and the positioning of soldering of the ballast and the installation of the ballast can be easily performed. Since the holes and the ballast mounting holes in the case can be easily aligned, assembly work is improved and defects caused by misalignment can be prevented. Easily automate tasks. In addition, the ballast positioning rib is equipped with an inclined part, and this inclined part serves as a guide when feeding the ballast, and
When the ballast is attached to the case, the distance between the ballast and the ballast is further increased, which has many advantages such as preventing deformation and discoloration of the ballast due to heat.
